Entropy generation in flow of Carreau nanofluid

This article examines hydromagnetic flow of Carreau nanomaterial over a stretched surface. Buongiorno nanofluid model is used in mathematical modelling. Here thermophoresis and Brownian diffusion are slip mechanisms under consideration. Energy equation is modelled via heat source/sink, Joule heating, nonlinear radiation and dissipation effects. The compact form of flow equations are changed to components forms through implementation of boundary layer concept. Suitable transformations give rise to ODEs. The obtained system is solved through homotopy method. The velocity, mass concentration, entropy generation, temperature, skin friction, Bejan number and Nusselt number are examined through graphical sketch. The obtained outcomes present that entropy generation boosts for higher magnetic parameter, Brinkman number and concentration ratio parameter while it diminishes via Brownian diffusion parameter.
